Show answer & explanation
Correct answer: B
Concept
Electronic computers are classified into generations by the core switching technology of each era. The historically established sequence is: First generation - vacuum tubes; Second generation - transistors; Third generation - integrated circuits (ICs); Fourth generation - microprocessors (VLSI); Fifth generation - artificial intelligence.
Application
Map each listed technology to its generation, then order from the earliest (first generation) to the latest:
Generation | Core technology | Listed item |
|---|---|---|
First | Vacuum tube | (C) Vacuum Tube |
Second | Transistor | (B) Transistor |
Fourth | Microprocessor | (A) Microprocessor |
Fifth | Artificial Intelligence | (D) Artificial Intelligence |
Reading the table top to bottom gives the chronological order: (C), (B), (A), (D).
Cross-check
The integrated circuit (third generation) sits between the transistor and the microprocessor but is not in the list, so it is simply skipped; the relative order of the four listed items is unaffected. The sequence therefore remains (C), (B), (A), (D).
